What This Code Means

Death of bone tissue in the right toe(s) caused by a previous injury or trauma.

Coding Tips

•Verify documentation specifies 'right toe(s)' and confirm whether one or multiple toes are affected
•Use this code specifically for toe involvement rather than general foot osteonecrosis

Clinical Significance

Right toe osteonecrosis following trauma affects the distal weight-bearing structures essential for balance and push-off during ambulation. While involving smaller bones, this condition can significantly impact gait mechanics and may require specialized podiatric or orthopedic management.

Documentation Requirements

✓Specific identification of right toe(s) involvement
✓Documentation of previous trauma to right toe(s)
✓Clinical or radiological evidence of bone necrosis in toe bones
✓Number and specific toes affected when documented
✓Assessment of gait impact and balance issues
✓Current pain levels and functional limitations
✓Treatment history and response to interventions
✓Impact on weight-bearing and ambulation patterns
